3M Aluminium Tape, 12mm Width, 55m Length - 7100229093


This aluminium tape provides a conductive, metal-backed solution for sealing, shielding and thermal tasks in industrial environments. It combines a silver aluminium foil backing with an acrylic adhesive to maintain electrical continuity and withstand broad temperature ranges common in automation, electronics and HVAC systems.

Features and Benefits:


• Conductive backing ensures electrical continuity and EMI screening
• Acrylic adhesive delivers 55N/100mm adhesion for secure bonds
• Operates from -54°C to +149°C for harsh thermal conditions
• 0.12mm thickness offers conformability with consistent strength
• Tensile strength of 49N/cm resists mechanical stress during installation

Applications


• Suitable for HVAC sealing and joint repair on ductwork
• Ideal for electrical shielding and continuity restoration
• Used for insulation wrap and thermal reflective surfaces
• Can be used for component earthing in electronics assemblies

How does the tape behave under repeated temperature cycling?


The acrylic adhesive and aluminium backing tolerate thermal excursions between -54°C and +149°C while retaining bond integrity and conductive contact.

Is the tape appropriate for mechanically stressed joints?


With a tensile strength of 49N/cm the foil resists tearing and supports applications where moderate shear and pull forces occur.

What standard testing relates to peel performance?


Peel and adhesion characteristics align with recognised test methods such as ASTM D-3330 to quantify adhesive strength.

Can it provide conductive connections on metallic and non-metallic surfaces?


The conductive aluminium backing establishes electrical paths on metal and can bridge to non-metallic substrates when a conductive contact is present.
